  • Substrates coated with organo-silanes that are sterically-protected
    Patent number: 4847159
    Abstract: This invention involves unique compositions consisting of substrates coated with organo-silanes that are sterically protected by a single bulky group. This material consists of an appropriate reactive solid to which is attached a silane whose silicon stom is bonded to a functional group that contains a dimethyl-substituted tertiary carbon.
    Type: Grant
    Filed: November 10, 1987
    Date of Patent: July 11, 1989
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Joseph L. Glajch, Joseph J. Kirkland
  • Structures surface modified with bidentate silanes
    Patent number: 4746572
    Abstract: A bidentate silane containing at least two silicon atoms bridged by certain groups, arranged to form at least a seven member ring system, is formed between the bidentate silane and the atoms to which the silane is covalently attached on the substrate surface.
    Type: Grant
    Filed: November 28, 1986
    Date of Patent: May 24, 1988
